Terms and definitions
Acronyms and terms used in the document:
- BT – Bluetooth;
- ELD – Electronic Logging Devices.
Introduction
This document contains information required for developing an application for receiving Electronic Logging Devices data via Bluetooth from FMC00A and FMM00A series devices.
The ELD synchronizes with the CMV engine to automatically record:
- Engine power status
- Vehicle motion status
- Miles driven
- Engine hours
- Identification of driver/authorized user, vehicle, and motor carrier
- Duty status
Configurable parameters
ELD functionality has 3 additional parameters:
| Parameter ID | Parameter Type | Default Value | Value Range | Value | Parameter Name | |
|---|---|---|---|---|---|---|
| Min | Max | |||||
| 40000 | Uint8 | 1 | 0 | 3 |
0 - Disable |
OBD Feature |
| 40002 | Uint16 | 10 | 2 | 65535 | Seconds | ELD data send period |
| 40008 | Uint8 | 0 | 0 | 1 | 0 - Disable 1 - Enable |
Send ELD data via Bluetooth |
ELD APP workflow
ELD functionality start to send data periodically via BT right after external BT device has been connected if OBD Feature (parameter ID 40000) is set to ELD (option 2). ELD data sending is paused if Configurator is connected. ELD data is resumed after configurator disconnects. ELD data sending resumes automatically when external BT device reconnects after connection loss.
